Greg Nicotero, Co-Executive Producer and Director of Special Effects Make-Up for AMC’s The Walking Dead, found himself surrounded by a horde of walkers at Universal Orlando’s Halloween Horror Nights 24. During his visit to the event on October 25, Nicotero experienced the real-life terror of his own undead creations inside AMC’s The Walking Dead: End of the Line haunted house.
